Have the patents for H.264 MPEG-4 AVC expired yet?

NO! ☹️ (in Brazil, China, Europe, Japan, Malaysia, Taiwan, and the United States)
YES! 😍 (elsewhere)

This article only considers H.264 Version 3 / High Profiles, which are the most common used profiles. These profiles were standardized in 2005-03-01, so only patents with a priority before this date are reported here, unless otherwise noted.

Most patents already expired, but some are still active somewhere:

For historical reference:

  • last patent in Canada, CA 2525937, expired on 2024-03-30.

The patent list managed by Via Licensing Alliance is available at: https://www.via-la.com/licensing-2/avc-h-264/avc-h-264-patent-list/

Expiration dates are according to "Google Patents" and may not always be correct. For example for US 7826532 patent Google reports an expiration date of 2027-11-29, while Via Licensing Alliance reports it as expired in 2023-09-04.

Patents added to MPEG LA patent list before 2012

Patents added to MPEG LA patent list since 2012

edit

These patents were added in the patent list after 2012 (according to https://scratchpad.fandom.com/wiki/MPEG_patent_lists#H.264_patents) and all have a priority before 2005-03-01 (specification release date of Version 3 / High Profiles). Someone should figure if they are essential for Version 3 / High Profiles or just needed for later H.264 Versions:

Options

edit

OpenH264 binaries from Cisco can be used free of charge.

Version 1 of H.264 (containing Baseline, Main, and Extended profiles) may have all patents already expired in some country (for example in Europe), you could consider using it.

Use other royalty-free codecs, like AV1, VP9, VP8, Theora.

Use codecs with expired patents, like MPEG-4 Part 2.
